Water-stop plug for adjusting water-draining of stool

ABSTRACT

A water-stop plug for adjusting water-draining of a stool comprises a cover, a water-stop washer, a small washer and a plug. The water supply of the water-stop plug for adjusting water-draining of a stool is adjustable according to the requirement of the user so as to save supplied water. By adjusting an air hole on a plug, the supplied water is adjustable.

FIELD OF THE INVENTION

[0001] The present invention relates to water-saving devices, and particularly to a water-stop plug for adjusting water-draining of a stool, wherein in the stool of the present invention, the water supply of the water-stop plug is adjustable according to the requirement of the user so as to save supplied water.

BACKGROUND OF THE INVENTION

[0002] Stool has become a necessary device for the currently life, but generally, the water supplied to the stool is unadjustable and a large amount of water is supplied for each time the stool is used so that water is wasted. Tools are necessary for adjusting water supplied to the stool, however, this is inconvenient, and thus the user can not determine the water to flush a stool each time the stool is used.

[0003] A prior art water-stop plug is illustrated in FIG. 1. In that prior art, a linkage 12 is controlled by the handle 11 so that a chain 13 is driven to pull the cover 15 of the plug 1 to drain water. Thus, the water in the water box drains out from a draining tube 17. A pontoon 14 is engaged with the chain 13. By adjusting the level of the pontoon 14, the speed of the cover 15 to cover an object is controllable so as to achieve the object of saving water. However, the disadvantage of this prior art is that adjustment of the pontoon 14 is insensitive and thus the object of saving water can not be well controlled.

SUMMARY OF THE INVENTION

[0004] Accordingly, the primary object of the present invention is to provide a water-stop plug for adjusting water-draining of a stool comprising a cover, a water-stop washer, a small washer and a plug. The water supply of the water-stop plug of a stool is adjustable according to the requirement of the user so as to save supplied water.

[0005] To achieve above objects, the present invention provides a water-stop plug for adjusting water-draining of a stool, which comprises a cover, a water-stop washer, a small washer and a plug.

[0006] The cover is a round piece with a diameter slightly larger than a diameter of the water box draining tube. A plug is coupled to the water-stop washer; one side of the cover is extended with a pair of symmetrical extending arms; a distal end of each extending arm is formed with a second notch. The water-stop washer is a round soft piece with a round hole at a center portion thereof; and the water-stop washer is mounted between the cover and the plug as a draining-preventing means. The small washer is a round hard piece with a round hole at a center portion thereof; and a plug is a hollow hemisphere. A top thereof is formed with a water inlet, and one lateral side has an air hole. A lower portion of the plug is extended with a flange.

[0007] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Referring to the appended drawings, the water-stop plug for adjusting water-draining of a stool of the present invention is illustrated.

[0014] With reference to FIGS. 2 and 3, an exploded perspective view of the present invention and a partial schematic view of the present invention are illustrated. The present invention has a cover 22, a water-stop washer 23, a small washer 24 and a plug 25.

[0015] The cover 22 is a round piece the diameter of which is slightly larger than the tube diameter of the water box draining tube. The center thereof has an annular rib 221. At least one notch 222 is formed on the edge of the annular rib 221. The edge of the annular rib 221 having the notch 222 has a reduced step to be formed as a buckle edge 223 for being engaged with the water-stop washer 23 and the small washer 24. Then a plug 25 is coupled to the water-stop washer 24. One side of the cover 22 is extended with a pair of symmetrical extending arms 224, 225. A distal end of each extending arm 224 (225) is formed with a notch 2241 (2251). Two posts 321 at two sides of the lower section of the water tube 32 can be coupled to the notches 2241, 2251. Thereby, the posts 321 are utilized as fulcrums and the backside of the cover 22 has a hooking hole 226 for hooking a chain 21. Another end of the chain 21 is hooked to the linkage 33.

[0016] The water-stop washer 23 is a round soft piece with a round hole 231 at a center portion thereof. The water-stop washer 23 is mounted between the cover 22 and the plug 25 as a draining-preventing means.

[0017] The small washer 24 is a round hard piece with a round hole 241 at a center portion thereof.

[0018] The plug 25 is a hollow hemisphere. A top thereof is formed with a water inlet 251, one lateral side has an air hole 252. A lower portion of the plug 25 is extended with a flange 253.

[0019] In assembly, the water-stop washer 23, small washer 24 and plug 25 are sequentially assembled to the annular rib 221 of the cover 22. By the notches 2241 and 2251 on the extending arms 224, 225 of the cover 22 to hook the posts 231 at the lateral side of the water tube 32, the cover 22 can cover the hooking hole 226 of the linkage 33 and the cover 22 (referring to FIG. 3). As a result, when one air hole 252 of the plug 25 is positioned at an upper side, as shown in FIG. 4, and the cover 22 is opened, since the water pressure of the water box will reduce with the reduction of the water level, the water in the water box will flow into the plug 25 from the water inlet 251. Thus the plug 25 become heavier. Thus, the cover 22 will sink downwards to cover a draining hole 31, but now the water in the water box does not drain out completely. Thus the water used is reduced. When the plug 25 is rotated so that the air hole 252 is positioned at a lower position (referring to FIG. 5), the water in the water box will drain out. Due to the water pressure effect of the water in the water box, it is difficult for the water to flow into the plug 25. As a result, the cover 22 covers the plug 25 slowly. Thereby, the water in the water box is drained out completely by the positioning of the air hole 252 of the plug 25. Therefore, the speed of the covering operation is controlled, and thus the water stored in the water box is adjustable.

[0020] The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
